section, the phenomenon has not changed, and Relay_log_file always on the same file.In order to find the cause of this phenomenon, we use strace to analyze. Because of the server phenomenon is very large disk write operations, so first use iotop to locate write a large number of thread ID, and then through the strace-p to analyze.The information collected through Strace is as follows:Read -,"376bin>303275t1721325322bg000k0000040005.5.31-"...,8192) = MaxLseek ( $,0, seekset) =0Write( $,"./

According to the reporter's understanding, at present, the only professional Mesh-Wifi equipment manufacturer in China -- Shanghai huichuang communication (GBCOM), in its MESH network, uses the multi-hop feature, A non-conventional seamless coverage technology-MESH terminal relay was developed.

DHCP RelayThe proxy can remove the need for a DHCP server in each physical network segment. It can transmit messages to DHCP servers not in the same physical subnet, you can also send messages from the server to DHCP clients not in the same physical subnet. Requirement Analysis Configure DHCP Relay on the vswitch so that the following users can dynamically obtain the IP address of the corresponding CIDR block. DHCP

The CONNECT request message is the same as the HTTP message, except that the method of the start line is connect. The response message does not need to contain the Content-Type header, because the connection only transfers the original bytes and is no longer the carrier of the message. 4. For the SSL tunneling mechanism, SSL is not required in the proxy. An SSL session is established between the clien

routers, commonly used network hardware devices, not only provide us with stable wired and wireless networks, but also some less common, but very important features. Recently, because the company's enterprise version of the router is unstable, decided to use a small router, set up a router group. However, in our general office of the two desktops, not to enjoy the function of wired Internet, because the router's line can not be reached in. On the Internet to buy wireless network card, due to its

DHCP relay principle 1 When the dhcp client starts and initializes dhcp, it broadcasts the configuration request packets on the local network. 2. If the local network has a dhcp server, you can directly configure dhcp without the need for dhcp relay. 3. If the local network does not have a dhcp server, the network settings with the dhcprelay function connected to the local networkAfter receiving the broadca

Along with the gradual expansion of the LAN scale, a network is often divided into multiple different subnets, so as to meet the work requirements of different subnets to achieve personalized management requirements. A large LAN usually uses DHCP servers to assign IP addresses to workstations. However, once a LAN is divided into multiple subnets, do we have to create DHCP servers in different subnets to provide IP Address Allocation services for workstations in each subnet? In this case, not onl
